Back in 81 it was R12 but the vehicle could have been retrofitted to take 134A, the best way to tell is look at the low and high side pressure ports, if it looks like they have had little fittings placed over the stock ones then it has been retrofitted to 134A if there are no caps then it is still R12.

If it is still R12, I would have it changed over to R134a. R134a is much cheaper, readily available and environmentally friendly.
